Question

class Time
{
   private: int hr, min;
public: Time operator+ (Time);
             Time(int x, int y) {hr =x; min = y; }
              void show( ) { cout << hr <<":" << min <<endl; }
};
Time Time::operator+(Time y)
{
Time z(0,0);
z.hr = hr + y.hr;
z.min = min + y.min;
if(z.min > 59)
{ z.hr++; z.min = z.min -60; }
return z;
}

------------------------------ Who can figure out what is going on with this main(), given the above Time definition? ------

void main(void)
{
Time a(2, 50), b(3, 40);
   a = a + b;

First, what is an equivalent way of writing "a = a + b; ?"

Explanation / Answer

Time a(2, 50), b(3, 40);
   a = a + b;

   adding hts 2 +3 = 5
   now adding minutes 50+40 = 90 since it is greater than 59
   hours++ = 5+1 = 6   minuts = minuts - 60 = 90-60 = 30

   a = 6.30

First, what is an equivalent way of writing "a = a + b; ?"
a = a.operator+(b);
